Vince Vaughn's Mystery Blonde

Vince Vaughn went to a London showbiz shindig, and ended up getting cozy with a yet-unknown blonde girl. Funny that she was attracted to him, as his shirt was apparently stained upon arrival, and his fly open as well.

So if he and Jennifer were actually ever together, and really didn't break up (as specified in US Weekly), I'm sure it will be officially over after this and we can all breathe easy.
